Hello, I have a problem with several streaming site players when going fullscreen. After 2-3 mins the control bar/ seek bar keeps poping up. I am using Chrome-Browser and tried aswell with Opera( Non-Extension mode etc.) [PC]. Do someone had the same struggle? I noticed, when I am watching on my TV via HDMI-output the problem seems to disappear. Maybe its part of the graphics card configuration or something, cannot find it out. thx for some suggestions. greetings
